Dartman vs Viper electronic dartboard

[Smobras]

Hi, i´d like to know your opinion about these two dartboards: Viper 787 and Dartman Ultra. For what i already read Viper has a lot of electronic problems and we have to buy an electrical adapter that is sold separately . About Dartman what i know is all about the smartbord model. I can get the Dartman here in Europe, and the Viper i think i can get it only from US or Asia, so the final prices are identical.
Let me know your opinion. Thanks in advance.
